BTEQBatch TEradata Query (BTEQ) is pronounced Bee-Teeeek.

BTEQ was the first utility and query tool for Teradata. BTEQ can be used as a Query tool, to load

data a row at a time into Teradata and to export data off of Teradata a row at a time.

The features of BTEQ:

BTEQ can be used to submit SQL in either a batch or interactive environment.o Fields

BTEQ gives the outputs in a report format, where Queryman outputs data in a format more

like a spreadsheet.

As said Bteq is an excellent tool for importing and exporting data.

There are mainly 4 types of BTEQ Exports.

Export DATA

This is set by .EXPORT DATA.

Generally, users will export data to a flat file format.This is called Record Mode or DATA mode.

If the data has no headers or white space between the data contained in each column and the data

is written to the file in a normal format.

Export INDICDATA

This is set by .EXPORT INDICDATA.

This mode is used to export data with extra indicator bytes to indicate NULLs in column for a row.

Export REPORT

This is set by .EXPORT REPORT

In this mode the output of BTEQ export would return the column headers for the fields, white

space, expanded packed or binary data.

Its just looks like a report with column headers and data.

Export DIF

This called as Data Interchange Format, which allows users to export data from Teradata to be

directly utilized for spreadsheet applications like Excel, FoxPro and Lotus.

Below is the example of BTEQ IMPORT Script.We are taking data form a flat file from C:\TEMP\

EMPDATA.txt and importing records into Empdb.Emp_Table.

.LOGON USERNAME/PWD;

.IMPORT DATA FILE=C:\TEMP\EMPDATA.txt, SKIP=2

.QUIET ON  

.REPEAT*

USING (EMP_NUM    INTEGER

      ,EMP_NAME   VARCHAR(20)

      ,EMP_PHONE  VARCHAR(10)

      )

INSERT INTO Empdb.Emp_Table

VALUES( :EMP_NUM

       ,:EMP_NAME

       ,:EMP_PHONE

       );

       

.QUIT

.LOGOFF

Below is a review of those commands for the above example.

QUIET ON limits BTEQ output to reporting only errors and request processing statistics.

REPEAT * causes BTEQ to read a specified number of records or until EOF. The default is

one record. Using REPEAT 100 would perform the loop 100 times.

The USING defines the input data fields and their associated data types coming from the

host.
